# How To Calculate The Estimated Day Of Birth Based On Hpht?

Doctor, I want to ask, when is my expected delivery? My HPHT on January 29, 2020. because I have already checked with the Puskesmas and clinic, but the estimated date is different u0026sup2; so I’m confused.

## 1 Answer:

Good morning, thanks for asking at HealthReplies.com. We understand your confusion. There are indeed a number of methods for calculating the estimated time of birth that might produce different results. In this answer, we will use the Naegele formula.

According to the Naegele formula, the estimated birth can be determined by adding 7 to the date of LMP, subtracting 3 from the month of LMP, and adding 1 to the year of LMP. So in your case, if your HPHT on January 29, 2020 or 29-01-2020, then the estimated birthday is 29 + 7 or the 5th, for a month minus 3 means October, and for the year it remains 2020 because when the month was reduced by 3, the year has decreased 1. In conclusion, the estimated birthday is October 5, 2020. The actual short way is to add 9 months from your HPHT, in this way, the estimated date might be incorrect, but the month should be the same.

But regardless of how many results you get with the calculation of health centers, clinics, independent calculations or our calculations, this is only an estimate. Which means, let's say you get the agreed numbers from all these places, it doesn't mean that your child will be born exactly on that day. It could be earlier, or later than that. Your child may be born 3 days, a week, two weeks, a month sooner or later than calculations.

So no need to worry about these results, because the different calculations will not affect your pregnancy. All you need to do is routine pregnancy control once a month for 0-6 months of gestation, once every two weeks at 7-8 months of gestation, and once a week at 9 months of gestation. In addition, consumption of vitamins and pregnancy supplements as recommended, avoid smoking, do not consume drugs without doctor's advice, limit physical activity, and adequate rest. When you have reached 37 weeks' gestation, you must be prepared because labor can occur at any time, regardless of what the estimated day of birth is calculated. So, hopefully answering your question.
